Yep this is the type of game that has things like item restrictions "based on pure mechanical rules with no connection to the world or lore". Believe it or not, that's something people are generally okay with, because it puts gameplay and functionality above 'realism' because realism clearly is not the goal of this RPG. Building the game like this very much caters to "common sense" because that's how RPGs have been built and that's what people expect.
What gameplay functionality?
I asked - what does this system bring to the table? How do these restrictions enchance gameplay?
Unless you cannot elaborate that, you have no argument.
That's how RPG's have been built? Yes it is. Do you always do something just because people have been doing it before you?
Past things and practices can be great, but they can also be crap. A bad legacy that doesn't die simply because it's become so common everyone got used to it. Kinda like if you lived in a sewer, you'd get used to the smell of feces and a sewer without that smell would feel wrong.
